Angles, and More Lines Below you can download some free math worksheets and practice. An angle bisector is a line that cuts an angle in half. It divides the angle into two congruent angles. To construct an angle bisector, you will need a compass and a ruler or straightedge. Here are the steps to constructing an angle bisector. 1  Place the point of the compass at the vertex of the angle.

- Question 6: Generalize what you know about the point of concurrency of the perpendicular bisectors of an acute triangle, a right triangle, and an obtuse triangle. The point of concurrency of the perpendicular bisectors, is the point where the three perpendicular bisectors of the triangle will intersect. If the triangle is acute they will meet at a point inside the triangle. If the triangle is obtuse they will meet at a point outside of the triangle.

- One loses the ability to say “base angles of an isosceles trapezoid are congruent” and “diagonals of an isosceles trapezoid are congruent”. Parallelograms would have to considered isosceles trapezoids. For me this is not a big deal: One just needs to say “base angles of an isosceles trapezoid that is not a parallelogram are congruent.”

Triangle Angle Bisector Theorem An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle.By the Angle Bisector Theorem, Proof: Extend to meet at point E. By the Side-Splitter Theorem, ---------(1). The angles are corresponding angles.So, Since is a angle bisector of the angle. By the Alternate Interior Angle Theorem, Therefore, by transitive property, Since the angles are congruent, the triangle is an isosceles triangle with AE = AB. Replacing AE by AB in equation (1), Example : Find the value of x.he angles are corresponding angles. So, Since is a angle bisector of the angle. By the Alternate Interior Angle Theorem, Therefore, by transitive property, Since the angles are congruent, the triangle is an isosceles triangle with AE = AB.

Bisection The most often considered types of bisectors are the segment bisector (a line that passes through the midpoint of a given segment) and the angle bisector (a line that passes through the apex of an angle, that divides it into two equal angles).n angle only has one bisector. Each point of an angle bisector is equidistant from the sides of the angle. The interior or internal bisector of an angle is the line, half-line, or line segment that divides an angle of less than 180° into two equal angles.
